25、土层，整平和碾压地基，浇筑钢筋混凝土临时便道等）。（4）供电设备：根据施工规模及设备配置情况，消防水池、地下泵房、污水池的中心点处放置 1台 630KW 变压器。（5）导墙施工（6）成槽机和其它配套设备的进场 2、总体部署消防水池、地下泵房、污水池、设备基础地下连续墙施工采用液压抓斗成槽机成槽，在拐角处和岩层深处成槽机不能施工的部位采用冲槽施工。根据现场施工条件地连墙施工的设备数量，近期计划进场1 台成槽机施工始发井两侧地连墙，随着工作面的逐渐展开再逐渐增加设备的数量，最终满足工期进度的需求。六、地下连续墙施工方法及工艺流程 1、施工工艺流程详见地下连续墙施工工艺流程文档编码:CO8B9V7B
